Question
A motor cycle is going on an overbridge of radius R. The driver maintains a constant speed. As the motor cycle is ascending on the overbridge, the normal force on it
increases
decreases
remains the same
fluctuates erratically
Solution
A.
increases
Reaction of normal force on the motorcyclist
As the motorcyclist moves upward on the bridge, θ decreases and therefore, N increases and becomes maximum at the highest point.
